i 'IMPROVEMENT IN ELEvAToRs ANbcARnlERs.

The Schedule referred. to lu these Letters Patentand making part of thesame.

I, TIMoTHr W."LA 0K0 IE, ofthe town of Worth, inthe county of Cook andState of Illinois, have invented certain new and useful Improvements inElevators and Carriers, of which the following is -a full, description,reference being had toV the accompanyn ing drawing,v making apart ofthis specification, in

i Figure 1 is a. top View.

\ FigureE, a longitudinal `vertical section.

Figure 3, a detail'cf the trip.

' Figure 4, 'a detached View of the dog, enlarged.

My improvement `relates "to that class of apparatus used for unloadinghay, coal, and other articles.

'In thedrawingy AA representtwo -ironV rods, from ive-eighths tothree-fourths of aninch thick,`oi` such length as may be necessary',theends of which are supported oncross-bars B B, which cross-bars, asshown, are pivoted at h to the supports G, the length of vwhich sup- 1`Vports depends .upon `the height at which the rods are to be placed.

p These rods may be about eleven inchesapart, and

they form atrack onwhich thewheels a move.

The several-parts D, together, forni afi-ame about one foot square,composed i of two 'transverse and six Between, each pairof the outerbars are two wheels,

a,about `four inches infdiameter, so arranged as to` frnoveuponthe rodsA; and between the two inner `'bars is a pulley, b, over which Vthe ropefr passesfto one end of' which' is .attached the weight w, to be raised,and at the other end is the power; i

A catch, '12,"is pivcted in -some suitable support, lt,

which can be secured to sornepart of the frame. -V l The catch ia soarranged lthat theend comes in coutactwith the rcpe 1f insuchga manneras' to permit' the rope top move-freely in the direction required toraise the weight, but prevent `its movement inthe opy wpositedirection.v

. i c isadcg, the rear end of which is forked, 'and eachV prong, d,is'pivoted-,upouone'of the -rods Aat-e,

. Two other prongs,4 g, extend downward and for- "Injc's anctclnl',which drops overand upon the `rear cross-bar c"the'f1'ame D, hclding'theframe in place while the'iweight is being elevated.

Tothe ropeis Vsecured a device for tripping-the dog,

topview of which is seen iniig. 3

i Itconsists of a central-piece, mthrough'whieh the rope passes, inwhich are `pivoted iour arms, 01 so that the arms `can be elevated butcannot fall below a horizontal position.`

This device is secured to thexrope by a set-screw, o, and can be raisedor lowered at will 'The frame D can be made of iron. The operation of mydevice is as follows:

. The position ofthe parts when the weight is ready to he raised isshown in iig. 2, the dog preventing the frame or-'car Dfrom being' drawnforward. The power being applied, thel weight will be raised -until thearms n of the trip vcome iucontact with the arms g of the dog, betweenwhich arms the rope passes, when the dog `will be raised, releasing theframe or car'. D, which lwill then be drawn forward upon the track A tothe v point where the weight is to be left.` After the weight has ,beendeposited the cala` must he returned to its former position. The armsu,being pivoted as descrihed, will, as the rope descends, pass throughbe'- tween the arms y. i l y VWhen theparts are inthe position shown infig. 2 the point of the Adog lholds up the catch i so vthat it does notcome in contact with the rope, which then" is free to move in-eitherdirection. t

There'is an advantagein having the trip adjustable at different pointson the rope, as the height to which the weight will be raised can hevaried.

lIfhere is also 4an advantage' iu yhaving the bars pivoted as described,as the track can be turned `a little to eitherk side to facilitate theattachment of the weight to the rope, since, when the -track is'tippedup on one side, thc rope can be carried further from the perpendicularline than otherwise without coming i in contact witlrthe arms g, but itis not essential to pivot the track.'

The track can be of any vdesired length, with. sunn ports at properintervals.

, ,The track may be somewhat inclined, so that theV car D, after theweight has been deposited, will run back by gravity; or it can be drawnback by meansof acord.

The elevated track can be readily removed from one place to another, nomattei' how-long, being made in suitablcsections.

The ends f of the prongs ll are' turned out seas to pass under the rodsA, forming stops, which prevent the dog from passing below a givenpoint.

The varms of thetrp will ,two oi' them, at least,-

Ycome in vcontact withthe prongs g in anypositiou which itwill'naturally assume.

, The track maybe stayed vat the ends by cords or i rods, and othersupports than O may be used.

What I claim. as new is as follows 1.V rlhe adjustable or swingingframe, consistingv of the rails A,secured to-V the end pieces B,thelatter VPeing pivoted to theirsupports, substantially Vas set ort 2,rlhe combination `ofthe swinging frame with the truck D, provided withthe wheels c, the pulley fas set forth.

b, and dog e, ail constructed and arranged to operate it to the rope,and having a. set-screw, o, or its equivsnbstantially asvdescribed.aient, whereby the trip may be adjusted higher or 3. The dog c,providedl with the arms g and d, and lower thereon, substantially asdescribed.

se pivoted to the rails a that it can be adjusted thereon TIMOTHY W.LACKORE. 'to hold the truck at any desired point, substantiallyWitnesses:
